Convertible folding ladder
A convertible folding ladder incorporates first and second rigid ladder sections, each comprising opposing spaced apart longitudinal rails, a plurality of spaced apart rungs between the rails, and a connector plate formed with one end of at least one of the longitudinal rails. Each connector plate of the first ladder section defines at least three spaced apart pin holes adapted for being selectively aligned with pin holes defined by the connector plate of the second ladder section. First and second fastener pins are adapted for being removably inserted through the aligned pin holes, such that the ladder is convertible between multiple different configurations.
